How to make PDFElement the default pdf reader instead of Preview

Question

I went to the support site and did what the page suggested and still no bueno. PDFElement still doesn't show as the default program to open pdf files in Evernote for example. How can I make that happen? Maybe a better question is how to select a different program than Preview to read pdf files. When I had Acrobat, the setup automatically asked whether to use Acrobat to read and work with pdf files by default - and it always showed as the default program . . .
